public Brush GetBackBrush(
GraphicsCache cache
)
Public Function GetBackBrush(
cache As GraphicsCache
) As Brush
| Name | Type | Description |
|---|---|---|
| cache | GraphicsCache |
A GraphicsCache object that provides access to the pens and brushes used for painting.

| Type | Description |
|---|---|
| Brush |
A Brush descendant representing the brush specified by the appearance object’s settings.

If the cache parameter’s value is not a null reference, the GetBackBrush method uses the GraphicsCache object to obtain the solid brush whose color is specified by the background color settings of the current appearance object. This lets you obtain the brush quicker as it may already be stored within a cache. Otherwise, a new System.Drawing.SolidBrush object with appropriate settings is created and returned.
Use the AppearanceObject.GetBackColor method to obtain the background color specified by the appearance object’s settings.
